From Harlequin's website:
The Revolutionists is a new play about four very real women who lived boldly in France during the French Revolution’s Reign of Terror. Playwright Olympe De Gouges, assassin Charlotte Corday, former queen Marie Antoinette, and Haitian rebel Marianne Angelle hang out, murder Marat, lose their heads and try to beat back the extremist insanity in the Paris of 1793.
